Elastic membrane for semiconductor wafer polishing apparatus



FIG. 1 is a bottom plan view of an elastic membrane for semiconductor wafer polishing apparatus showing our new design;

FIG. 2 is a top plan view thereof;

FIG. 3 is a front elevation view thereof;

FIG. 4 is an enlarged perspective view of a portion taken along section 4 in FIG. 2;

FIG. 5 is a cross sectional view taken along line 5-5 in FIG. 2; and,

FIG. 6 is an enlarged portion view taken along line 6-6 in FIG. 5.

The broken lines shown in the drawings represent portions of the elastic membrane for semiconductor wafer polishing apparatus that form no part of the claimed design. The dashed-dot-dashed lines represent the boundary lines of the claimed design.

All surfaces not shown form no part of the claimed design. 

CLAIM The ornamental design for an elastic membrane for semiconductor wafer polishing apparatus, as shown and described.
